Another object of the invention is to provide an improved machine of 'this type inwhich the pipe is supported and driven through a chuck adjacentone of its ends and an internal grip at the other end at which the shaping mechanism is located, so that the pipe will be driven at bothends. This is advantageous when the pipe is thin.

so that deformation by torsional'stresses is.

impossible.

Another object of the z invention is I to provide an improved machine in which the sup iiorting head for the chuck at the end ot the pipe which is remote from the shaping mechanism is quickly adjustable so the machine can be set to operate on pipes of difterent lengths and so as to avoid the necessity of adjusting the supporting mechanism for the pipe adjacent the shaping mechanism. I

Qrnother object of the invention is to provide means for uniformly and conjointly adjusting the supporting rollers forthe end ot' the pipe which is being shaped.

Another object of the invention is to provide for longitudinal adj nstrnent of the internal chuck adjacent the end of the pipe which is to be shaped to adapt it to hold the pipe for dilferent kinds of shaping such as Hanging or corrugating.

Another object of the invention is to provide quickly op -ble means to eflectcross adjustment of the carriage which carries the shaping mechanism, to bring it into and out of its operative position, so that the pipe may be loaded into the machine from the end at which the shaping is done.

Another object of the invention is to provide improved mechanism for operating by power the mechanism for shifting the shaping roll arriage.

Other objects oifthe invention pear from the specification.

The invention consists i features hereinafter set forth and more par- {4 l "ill aplrrly defined by claims atthe conclusion end at which it is shaped.

Fig. 12 is a section on line 12-12 of 8.

, The invention is exemplified in a machine which comprises a series or rollers a for eri ternally supporting a length o'l pipe to be shaped adjacent the shaping mechanismja chuck Z) for internally gripping and sup: porting the same end: of the pipe and adj acent the rolls a; and a chuck 0 for supporting the other end of the pipe. An impor- 8e tant feature of the invention consists in. internally and externall supporting't-he p pe at the end which is being shaped so as to prevent irregular detormation'ofthe metal and tolocalize the shaping or bending of the metal to the portions or points desired. The pipe cl, which is to be shaped, is insert able into the machine from the end at which the" shaping mechanism is located and the chuck 0 is longitudinally adjustable to and from the internal chuck and rollers a to adapt the machine for shaping pipes of different lengths withoutlongitudinally shifting the rollers a and the internal chuck.

The chuck 0 comprises a head 22; jaws 23 which are radially slidable in channels 24 in the head 22, are radially adjustable by screw-shafts which are suitably journalled against endwise movement in the head 22, and are provided at the outer ends with terminals 25- adapted for the application of turning tool; pinions 26 fixed to the inner ends of shafts 2 9 respectively and a gear 27 for effecting conjoint and uniform adjustment of the shafts .4 so that the jaws 23 will be equidistantly moved to or from the axis of the pipe (Z. The internal which are mounted in a bracket 4-0.

adapt the machine for pipes of different chuck 5 comprises a head 28, which is fixedly secured to the shaft e, and jaws 29 which are radially slidable in the head and are adapted to grip the inner periphery of the pipe (Z. Jaws 539 are radially shiftable into and out of engagement with the pipe by wedge members 30 fixed to the jaws and a wedgel1ead 31 which is axially movable relatively to the jaws and fixed to a longi tudinz-illy movable shaft 32. Shaft 32 c tends longitudinally through shaft (2 and fixedly connected to a piston 38 which. is slidalole in a cylinder 3A and is adapted to be operated to adjust the internal chuck by fluid-under pressure admitted to the eylinder 34C. The latter is fixed to the outer end of shaft (2 so that it and shaft 32 will rotate with shaft 6.

Shaft 6 extends rearwardly through and beyond chuck 0 and is sup 'iorted at its rear end by a bracket gear 36 which maybe driven by any suitable mechanism, as well understood in the art. Said shaft extent through the sleeve, which is journalled in the bearing 38. A key on sleeve 37 extends into a longitudinal key-way 6, so that the driving; relation between them will be maintained while the sleeve is adjusted to different positions along the shaft. Said bearing; 38 is provided with laterally projecting studs or pintles 39 To lengths, mechanism is provided for longitudinally adjusting the chuck c relatively to the chuck Z) and rollers a and to facilitate the adjustment, motor-driven mechanism is provided. For this purpose, the supporting bracket 40, which is formed of sections scoured together by bolts all, is lit-Iedly cured to a carriage 42 which is formed with shoes l?) adapted to slide on four rails -ll. An electric motor 45 is n'iounted on an extension of the carriage 4-2 to operate the gearing for longitud nally shifting the carri e to adjust the chuck c. This gearing prices a pinion so on the motor shaft; :1 near 4.7 meshing with pinion 4L6 and fixed to a c ss shaft 4-8. which is mounted in bearing mounted in the carriage 42; a worm on shaft 48; a worm-wheel 51 driven by worm and tire to a or s-shaft 52 which is journailed in bearings :35 on the carriage; pinious 54. k yed to shaft 5 pinious 55, meshing with pinions 54: respectively and mounted on stubshafts 56, which are mounted in the carriage 4:2. and gear racks 57 w th which pinions mesh respectively. A rack 57 is provided between each pair of rails 44. li o-rm 50 is enclosed in a housing 58 formed in the carriage 42 and worm-gear 51 is also enclosed in said housing and in a remicylindrical housing section which is removably secured to the carriage. Motor 415 is of the reversible type so that. it may be operated in either Shaft c is driven by a direction to drive the gearing to sp edilv shift the chuck c longitudinally of the ma chine to adapt it for shaping pipes of dif ferent lengths.

The rear end of shaft 6 is secured by a key (Sl'to rotate with a sleeve (it) which is journallel a d held aga nst cadwise :i'aovement in a bearing (52 which provided with laterally projecting studs 62"" which are pivotally held in bracket The purpose in iivotally supporting the shaft 6 by means of studs 39 on bearing 88 and studs 6 on hearing" is to make it possible to correctly align or position the Chuck 1 which is at the front end of the shaft, wi. out cran'iping the shaft in its hearings or causing; undue wear. 7

In performing different shaping opera ti one on the front end of the pipe, for example, such as shaping and corrugaling, it is son'ietinies necessary to longitudinally adjust the internal chuck 7) relatively to the stationary supporting rollers a, and for this purpose shaft 0 is longitudinally adjustable in sleeve 60. Said shaft is provided with screw-thread 63 and nut Sit on said thread and also with sc ew thread 65 witha nut 66 thereon. The shaft 6 is slidable in sleeve 60, and, by adjusting the nuts 64:, 66, the entire shaft'may be adjusted longitudinally. Key 61 is adapted to slide in a key-way in sleeve 60. Gear is keyed to sleeve. The driving connection between gear 36 and shaft 0 is maintained in its different adjustments.

The rollers a are radially adjustable to adapt them for supporting and rotatably guiding pipes of different diameters and to shift them into and out of operative position to permit placement and removal of the pipe into its o 'ierative position irom the front of the n'iaehine. These rollers and the mechanism for Sl1})PO1tlDg and shifting them are mounted in a frame F which is composed of upright I-beanis 67 which have their lower ends fixedly secured and embedded in the machine base and plates 68 secured to said beams so as to form an approximately rectangular rigid supporting structure. four rollers a are provided to support the pipes 90 apart. Each roller mounted on a shaft '?0 which is carried by a slide 71. Each slide 71 is slidable radially in a guide 72 which is formed of members fixed to the frame F. Each slide is radially movable by means of a screw-shaft 73 which is threaded to the guide and has its outer end held against longitudinal movement in a. hearing The i l. A bevelled pinion 'T is fixed to the outer end of each shaft 73. These shafts '13 are ared together for conjoint adjustment to uniformly shift the rollers a by means of connectin shafts 76 with a bevelled pinion 77 at either end for meshing with pinions Two of the shafts 76 extend vertically between the upper and lower screw-shafts and curved guide casing upper shafts 73. Said horizontal shaft 76 'is mounted in bearings 77 carried by the frame. in practice, it is desirable to operate the ro lers a, qnckly to facilitate the operation of the machine and for this purpose a reversible electric motor 78 is mounted on top of the frame F and is provided with a pinion 79 which meshes with a gear 80 on said shaft '76-. This exemplifies motor-driven iuechani for conjointly and equidistantly in radial direction, adjusting the rollers a in the stationary frame F.

A pair of rolls 9', 9, adapted to engage the inner and outer peripheries of the front end of tee pipe (Z, which are adapted to swing horizontally to fo "m a flange on the pipe, exemplify means for shaping the pipe. These rolls are mounted in an arcu'ate slide 81 which fits and is held in a correspondingllo'll g is journailed on a stud 83 which 1.. fined in slide 81. Roll 0 is sustained so it may be shifted to and from roll 0, being carried by a stud 84 which is held in a slide 85 and a cap 86. A screw 87, oi'ierable by the hand wheel is held against longitudinal movement in cap 80 and extends through the slide 85 to shift the roll 9 into and out of operative relation with the roll g, so that pipes of different thicknesses may be grasped and shaped by these rolls.

asing I 82 is integrally formed with a frame to serve as a carriage for power (lriven mechanism for swi ing the rollers g. This mechanism comprisesa reversible electric motor ,1

.. to the shaft of which a pinion 92 is secured, which is adapted to drive variable speed transmission 93 in a housing 94 on said frame; a shaft 95 driven by said transmission gearing, a bevelled pinion 96 fixed to shaft 95, an internally toothed bevelled wheel 97 fixed to a shaft 98 which is mounted in bearings 99 in the'casing 82; a worm 100 on shaft 98 and meshing with teeth 101 fixed to the periphery of arcuate slide 81. By operating the motor 91, the shaft 98 will be driven to swing slide 81 and the shaping rolls 9, g. This power mechanism facilitates the work and furthermore makes it possible to shift the shaping rolls at a regular and regulated speed.

The frame 90 and the parts carried thereby, including the motor 91, the shaping rolls and the gearing for swinging them, is movable longitudinally of the pipe, so that the shaping rolls can be shifted into and out of operative relation with the end of the pipe and is movable transversely so that said rolls may be shifted transversely to separate them from the formed flange and also so that the shaping mechanism can be shifted transversely out of the way, so that pipe'may be loaded and unloaded into the machine. For

thispurpose. frame 90 is guided and longitudinally slidable inways 102 in a carriage 103 transversely, and guided in ways 10f formedin' a frame 105 which is fixedly supported on the base of the machine. A screw 106', journalled in bearings 107 in carriage 103, is threadedto a nut or runner 108', which is no'n-rotatably held between depending lugs 109 on the frame 90 and a hand wheel 110 is fixed to shaft 108 at the front end of carriage 103. By rotating said hartchwheel, the frame 90, with the shaping rollsfland mechanism for operating them, may be moved longitudinally to shift the rolls into operative relation with the end of the pipe. Power operating the carriage 103 transversely to move the shaping mechanism to one side of the pipe after the latter has been shaped to permit the pipe to be removed from the lugs and for rever 'ely shifting said mechanism after. a pipe has been placed in operative position on the lugs, comprises an electric motor 11]. fixed to the top of carriage 103; a pinion 112 on the motor shaft, a gearwhe'el 113 meshing with pinion 112, a transverse screw-shaft 114 carried in bearings 115 and 116, on carriage 103 and operatively condriven mechanism for nected to a non-rotatable nut 11?, which is confined against longitudinal movement with the screw by lugs 118 on frame 105. To shift the carriage 103 and the parts carried thereby transversely, it is only neces sary to switch on the motor accordingto the direction in which the carriage is to be shifted. This exemplifies power operated mechanism for quickly shifting the shaping mechanism transversely into and out of its operative position. For convenience of the operator, a platform 119 is provided at the front end of the machine and this is suspended from carriage 103 so that it will be transversely adjusted with the carriage 103.

The operation is as follows: Normally, the shaping rolls and carriage will be disposed to one side of the ilrive-slfiaft c that a suitable truck, adapted to run on rails f1 and carrying a length of pipe to be shaped, may be run into position to deliver the pipe where itcan be pushed backwardly between rolls a and into the chuck 0. The jaws 23 of chuck 0 are then tightened and rollers a will be adjusted by the operation of motor 78 and the intermediate gearing, so that the rollers will engage and support the front end of the pipe. Fluid under pressure will then be admitted to cylinder 34 to operate shaft 32 and expand the jaws of chuck b, so thatthe pipe will be internally gripped adjacent the rolls a. As well understood in the art, the pipe to be flanged is usually heated Where it is to be shaped and, therefore, it is important that the front end of the pipe be supported and gripped so as to avoid undesirable deformation of the pipe.

Power will then, he applied to gear 36 on shaft e and the latter, through external chuck 0 and internal chuck b, will rotate the pipe. After the pipe has been gripped and placed in its operative position, the carriage l( will be shifted transversely by the operation of motor ill to bring rolls g, 9' into alignn'ient with one side of the pipe. The hand-wheel 110 will then be operated to shift the frame longitudinally to bring the rolls o', 9" into o tire relation, with respect to the end of the pipe, as shown in Fig. 8. Motor 91 will then be operated to swing slide 81 in the casing 82 while the pipe is in rotation to form the flange on the front end of the pipe, as shown in Fig. 10. lVhen this shapii'ig operation has been completed, rolls r 9 will. be disengaged from the pipe flange and the carriage 103 will we operated transversely until it is located at one side of the pipe, so that the latter may be withdrawn from the chucks and shaft 0 and thereupon the machine will be again operated as before, it be ng understood that the rolls 9, g will be swung reversely, so that they may be brought into operative engagement with the pipe end by the longitudinal rearward shift of the frame.

The invention exemplifies a machine in which the pipe is held by an internal chuck and externally supported by rollers at the end where the shaping is done, so that irregular deformation of the pipe is prevented and the shaping is localized to the desired point; also a machine in which the internal chuck is operated by a pipe which extends rearwardly and is driven at its rear end; also one in which the chucks at both ends of the pipe are driven in unison to avoid deforn'iat on of the pipe; also one in wnich the chuck, which is remote from the shaping mechanism, is quickly and longitudinally adjustable by power to adapt the machine for pipes of ditfirent lengths; also one in which the rolls for supporting the outside of the pipe adjacent the end being shaped quickly adjustable by power dri en ieci sin; alsoone in which the carriage,

which the naping mechanism is mounthe s; cklv operated by power into of its opri tive position in front of also one in which the internal be adjusted longitudinally relato the supporting rollers at the end of the pipe to be shaped, so that the chuck and rollers may be coactively arranged as desired for dillercnt shaping operations, such as forming flanges of different lengths or for otherwise shaping the end of the pipe.

T he invention is not to be understood as restricted to the details set forth, since these may be modified within the scope of the appended claims, without departing from he spirit and scope of the invention.

Having thus described the invention, what I claim as new and desire to secure by Letters Patent, is: y
